    Hitachi HT-550

    Hi, I have the HT-350 model, I think has the same motor as the 550. MIne is overspeeding, the speed control still reacting but still too fast. All caps was change, all semi-conductors are ok and I even change the IC. I noticed, if you help the platter to spin faster, it doesnt slow...

    Yamaha CA-1010 recap

    This is a very strange problem... I accidentally made mine in protection mode while I was doing connections on the phono.... The amp is OK. Mine is more than 1 hour before the relays clicks. The delay cap I believed C403 is ok. I checked all the components on the protector but I didnt found...

    Yamaha CA-1010 recap

    I also have CA-1000 III, identical to CA-1010. Im planning to re-cap it this week, questions on the capacitors.. 1) Original 1000uf 6.3v on the amp side are as about the size of my middle finger (diameter). The available here are so little about the size of a pencil, so small compare to the...

    Onkyo Integra A-819GT (hot heatsink)

    I lied and I need HELP! Upon closer inspections, there are several pairs (left and right) of darkened resistors, slightly burned, cant read the codes. These are located near the servo unit with plastic exclosure.. Im sure these something to do with the excess heat generated by the drivers...

    Onkyo Integra A-819GT (hot heatsink)

    all ok (Moderator pls delete this post) bias voltage are normal.... everything is normal. The heat I felt is not generated only by the output transistors heat sinks, there are others that are contributing such as the pre-driver transistors and on the right that are mounted on smaller heat...
